London, United Kingdom--(Newsfile Corp. - November 11, 2020) - Meridian Mining SE (TSXV: MNO) ("Meridian" or the "Company") today announces that it has advanced the program to identify future priority areas for the planned confirmation infill and extensional drill program over the historical Cabaçal Cu-Au mine. An open southern zone of high grade Copper (Cu) Gold (Au), Silver (Ag) and Zinc (Zn) Volcanogenic Massive Sulphide ("VMS") mineralisation was intercepted by the historical drilling completed by BP Minerals and Rio Tinto (Figure 1). This provides a low risk, high priority area to advance the future Cabaçal resource delineation and confirmation program.
Highlights of the Historical* southern drill results at Cabaçal:
Underground Diamon Drill Hole ("DDH") CAIK-211 returned:
29.3 m @ 6.04 % Cu, 3.10 g/t Au, 28.81 g/t Ag and 0.65% Zn
Surface Diamon Drill Hole ("DDH") DDH 482 returned:
15.0 m @ 5.50 % Cu, 1.31 g/t Au, 24.72 g/t Ag and 1.20 % Zn
Historical surface DDH 596 intercepted:
13.4 m @ 5.2% Cu, 2.66 g/t Au, 9.54 g/t Ag and0 0.49 % Zn
Meridian's southern zone focus is aided by an independent report prepared for Rio Tinto by the Geology Department of Queens University, Kingston Ontario1. The report was completed in mid-1990 just prior to the mines' closure used exploration and mining databases provided by Rio Tinto at the time. This southern Cu-Au zone extension's potential as defined by the DDH CAIK-211, DDH 482, and DDH 596 within the report will be one of the initial focus areas for the Company's advance of the project.
The Company sees the future use of a Bore Hole Electromagnetic Survey ("BHEM") down hole tool to direct the targeting of these high-grade zones of Cu-Au VMS mineralisation as a major advantage compared to historical DDH programs. The use of BHEM tools is a standard practice in today's exploration and resource delineation programs for sulphide hosted bodies.

*Samples for Cabacal drill programs were historically analysed by for gold by 50g Fire Assay with AAS finish, copper three acid digest and AA finish, and silver by Aqua Regia by AA finish at BP Mineral's laboratory at Bonsucesso (Rio de Janeiro, Brazil),. Samples were prepared at Caxias and the mine site itself. Half-core was dried, crushed to a quarter inch size through a jaw crusher, pulverised to 150 mesh in a ring mill, passed through a Jones Splitter to produce a 100-200g split, with one sample archived for reference and the other dispatched for analysis. BP Mineral's quality control program included duplicate analyses, and periodic checks using independent laboratories. Holes were surveyed by theodolite referenced to a local base station by qualified surveyors. Analytical results are variably recorded in prints of BP Mineral's VAX database records of the time and reports of the era. An objective of Meridian's initial drill program is to conduct a series of twin drill holes with a modern QA/QC program. True thickness of intersections is estimated to be 80-90% of down-hole width.
